LDCM is the company's 145th satellite to be launched since 1982, including 76 commercial and 69 government spacecraft. Once its checkout is completed, it will join Landsat 4 and Landsat 5, two earlier Orbital legacy spacecraft that have supported the Landsat program for three decades.

Orbital designed, built and tested the LDCM satellite under a contract from NASA's Goddard Space Flight Center (GSFC) at the company's Gilbert, AZ manufacturing facility.

Lift-off took place at 10:02 a.m. (PST) and the satellite successfully separated from the rocket's final stage 78 minutes into the mission, placing it into an initial orbit about 410 miles above the Earth, from where LDCM will later raise its orbit to a final altitude of 438 miles.

The mission operations team has confirmed that it is able to command and communicate with the satellite and that its solar array, which provides electrical power to the two onboard scientific instruments, is fully deployed and operating as designed.

NASA and the U.S. Geological Survey (USGS) share responsibility for the LDCM program. NASA's GSFC oversaw development of the flight systems including the LDCM spacecraft and the onboard instruments, and is responsible for mission operations, launch, and in-orbit checkout. The USGS will operate the satellite and the Landsat ground network, image-processing and archive facilities.

"It was a smooth launch and deployment for the LDCM satellite earlier Monday and it is now performing very well early in its mission," said Mr. Mike Miller, Orbital's Senior Vice President of Science and Environmental Satellite Programs.

"The LDCM satellite will enable the USGS and NASA to maintain the longest continuous record of Earth environmental data gathered from space. We are honored to have been an integral part of this legendary program that provides critical Earth observation data that benefits millions of people and a wide variety of industries worldwide."

Over the next several weeks, Orbital's LDCM engineering team will support NASA and USGS with in-orbit testing of the satellite to verify all systems are operating as planned. Once LDCM is fully tested, USGS will operate the spacecraft and collect data from multiple ground stations worldwide.

"We are incredibly proud of our dedicated team who designed, built, tested and participated in the launch of this remarkable observatory," said Daren Iverson, Orbital's LDCM Program Manager.

"Monday's launch is the culmination of over five years of precise engineering and high-tech craftsmanship, along with proven science-gathering technology, coming together to provide a closer look at our planet.

"It has been an extraordinary experience to be part of this program and to partner with our NASA and USGS customers. In the future, we hope to continue our critical role in their mission by building the next generation of Landsat spacecraft."

With an anticipated service life of five years, LDCM is based on the company's flight-proven LEOStar-3 standard modular spacecraft platform that reduces assembly and test-cycle times. This low-Earth orbit "bus" has served as the platform for several other highly successful NASA-sponsored Earth and space science missions, such as Swift and Fermi.

US launches Earth observation satelliteLos Angeles (AFP) Feb 11, 2013
The United States launched its latest Earth observation satellite Monday atop an Atlas V rocket from Vandenberg Air Force Base in California, NASA said.
The Landsat Data Continuity Mission, or Landsat 8, was the latest in a line of satellites used to continuously gather imagery from space of the Earth's land surface, coastal areas and coral reefs.
